Be it known that I, MARoELLUs Conn, a citizen of the United States,residing at Washington ,in the District of Columbia,have inventedcertain new and useful Improvements inFiltering Apparatus, of which theAfollowing is a specification. Y

My inventionrelatesto improvements in lters; and it pertains to ailterwhich is adapted to supply ltered water to houses, hotels, andother places Where filtered water is desirable.

One object of my invention is to provide a filter consisting of twoparallel cylinders, one constituting a primaryfilter and the other asecondary purifying or final filter, the inlets and outlet therewithbeing so arranged that Water is conveyed from y the1 main upward throughthe primary filter andthe'n returned and carried upward through thesecondary or final lter instead of filtering fromthe top of thefiltering cylinders or chambers, as is usually the case.

i A further object of my present invention is to so construct the watercommunications with these filtering cylindersor chambersj that they canbe easily cleaned either simultaneously or separately by reversing theflow of the water from the mainfthat is, by causing it to move downwardand through the lower end of the filtering chamber or chambers-or bymeans of whichcommunication and their controlling-valves the cylinderscan be separately and independently washed or liushed with water whichhas been previously cleaned by passage through the other chamber orcylinder, or by means of said water communications and their controllingmembers or valves water can betaken directly from the main and carriedtothe point of con-` sumption without passing through either of4 thesaid filtering-chambers, or water can be taken from the main and carried-through either one of the filtering-chambers independently and thenconveyed to the source of consumption. Y

A further object of my invention is to provide a vertically-arrangedcombinedsupplying and settling chamber into which the water first passesbefore it enters either of the said filtering-chambers, whereby thewater in standing will settle and the sediment be collected inthe'bottom of the said combined su pplying and settling chambers,whereby when the filter is being used the water from the combinedsupplying and settling chambers is first carried through' the filter,thus having the advantage of` first settling the water be- `fore it isfiltered, and thus relieving the filters 'of a considerable amount offiltering which is required where the water is taken directly to thefiltering-chambers without any settling operation. These combinedsupplying and settling chamberswill preferably be ofa size sufficient tofil'lan ordinary receptacle-such `as a pail, pitcher, or pan.

The object of -myinvention pertains, further, to the specificconstruction and arrangement of the parts, all of which will be fullydescribed hereinafter and particularly referred to in the claims. Theaccompanying drawing is a vertical sectional view, the pipes beingpartly shown in full lines, of a filtering apparatus embodying myinvention. f

Referring now to the drawing, A indicates a vertically-arran gedprimary-filtering chamber or cylinder, and B a secondaryverticallyarranged lfinal-filtering or purifying chamber which isarranged parallel and adjacent to the vprimary cylinder A. Each of thecylinders lor chambers'areihere shown as provided, respectively, withthe supporting-pedestals C and D, thoughthey may be otherwise supported,if desired. Situated below and in communication with the bottoms of eachof these vertically-arranged filtering-chambers `A and B arethe`combined supply and settling chambers E. Situated between the upper endsot' the combined settling and supply `chambers E and the lower ends ofthe filtering- `chambers A andB, respectively, and establishingcommunication between the settling and` supply chambers E and the sai dfiltering- `chambers are castings I, and situatedat the upper ends ofthe chambers A andB are similar castings or connections L and M,respectively. Each of these castings I, J, L,- and M are provided withlaterally-extending shoulders a, against which are placed suitablesieves b, and the sieves b are clamped, respec- IOO tively, between theupper ends of the combined supply and settling chambersE and the ends ofthe short pipes K or connections,wl1ich project, respectively, from theupper and lower ends of the said chambers or cylinders A and B. Each ofthese castings I, J, L, and M are providedA with laterally-projectingflanged openings cl, which are providedwith closing-plugs e, andsituated within these castings, between the sieves b, Vis material o.

The object of the laterally-projecting 'openings d is to permit theready insertion or re-'Y moval of the sponges orjequivalent material cfor thepurpose of removing them fonthe.V

purpose of cleaning or for'the purpose of substituting new sponges andalso for, the

v purpose =of vfacilitating the insertion of the Sponges intheir properposition when 'the iltersare manufactured. l G is a pipe whichcommunicates with th water-main, and projecting from this pipe,

near= its `lower end, 'is a pipe P, which has communication with thelower end of the com- `nined supply and settling chamber E, which is in.communication .with the primary-ilterin g chamber:A,-and alaterally-projecting pipe Q, which is situated above the pipe P and incommunication with ythe chamber E,- which is belowiand in communicationwith thenalfiltering chamber B. The pipe G, between the pipes P and Q,is provided with a valve l, by means of which the flow of the water-iscontrolled, and'l the pipes P and Q are each respectively provided withthe valves 2 and 3 for the samepurpose. Y n

Extending across the upperends of the chambers A and B is a pipe N,having one end in communication with the upper end of theprimary-filtering chamber A and its opposite end N being theoutlet endof the pipe, which 'is in communication withv the house or other sourceof consumption. A valve 4 is situated just abovey the casting L, at theupper end of thechamberA, and a valve 9 is `situated just above thecastings M, atthe upper end of the chamber B. Depending from the pipe N,at a point between the inlet end of the pipe N andthe pipe V, whichestablishes communication between the pipe N and the upper end ofthechamber B, is a pipe T, which hascom.- Y munication at'its upper endwith the pipe `N andA at its lower end with the pipe G, thatcommunicateswith the water-main. Situated bef, tweenithe valve 4 andtheupper end of the pipe Tis a valve 5, and depending from the pipe .N,between the valve 4 and the valve 3,

is a cleaning'or flushing pipe S, which extends downward within thekchamber A and is provided Ywith. a plurality of perforations,throughswhich the water, will iow into the chamberA. 'A similar pipe S`is provided for 'the finalffllter-ing chamber B, and the upper end ofthispipe is in communication-with `thepipeN, betweena valve'7 and the-pipe'V,

and, this pipel'S is provided with a val-ve 8.Q

Situated in the pipe N is another valve 10, which is located between thecommunication V with 'the upper end of the final-filtering chamber B andthe outlet end of the pipe N. These valves serve in al manner which'will be hereinafter described to control the ow ofthewater 4through thefiltering-chambers and also to control vthe iiow of the waterindependently ofthe ltering-chambers.

'Projecting'from the lower portion of the Ipipe T andin communicationwith the lower ends of the chambers A and B are the pipes R, eachA .ofwhich is provided with controllingvalves 12, and these pipes Rare usedfor the purpose of assisting with the-cleaning or flushing of thechambers A and B by reversing` thelow of the water through them when itV.is desired toclean the filter.

- The vprimary-fineri'ngchamber-A is fined' lwith-.sharp sand andcrushed stone A', and

the final or purifying filtering chamberB is filled with charcoal B'. -A

The bottoms of each of the combined `supf `ply and settling chambersEare provided with plugs vor valves g, bymeans of which they may beopened'for the passagexof the sediment through these chambers E and intosuitable receptacles placed therefor, or, if desired, these outlets gmay be Vconnected /inany suitable manner with the sewer.

The operation ofthe filter when using both of the filtering-chambers(which is thel preferred operation of the apparatus) forfiltering thewater is as follows: The valves k,1,

12, 6, 7, and 8 are closed and the valves 2, 4, 5, 3, 9, and lO areopen.The lwater-passing from the water-main passes into thepwipe'G,

chamber E, wherethe water stands whenth filter is not inuse, and theheavyv matter held in suspension within the water settles -to the bottomof the said chamber. Whenthe supply endN. is opened lin 'the house orother point Vof consumption the water whichv1 has settled in thesettlingchamber E jpasses through the sponge C', through the primary`chamberA, the pipe N, down the pi pe- 'Rand into the lower portionv ofthe combined set tling and supply chamber E. Attheubottom of thefinal-ltering chamber B,-passes through the sponge at lthe upper endofthe settling and supply chamber E, through the chamber Band the pipe Vinto the pipe N and tothe point of consumption.- When it is-desired touse the water direct from lthe main without filtering `it,the valves 2,3, 12, 5, 9, and8 are closed, when the'water will pass directly from thewater-main to the point of consumption. Ifit is desired to'have thewater pass only through the primary-lteringchamber A, the valves 1, 3, 68,y and 9 are closed, when the water will pass Ythrough the primary'filterer andonI to-its source ofconsumption.

Should -it bedesired topass'the water Ythrough TOO `through the pipe P,and into thev lowerV por- :tion of the combined settling andsupply .IIO

SVO

only the filial-filtering chamber B,the valves 2, 13, 12, 7, and Sareclosed, when the water will flow through the nal-filtering chamber B tothe source of consumption.

Attention is particularly called to the fact that in the use of thefiltering apparatus of the construction shown the filtering is done fromthe bottom of the filtering-chamber, which is considered the propermethod of filtering, rather than from the top of the chamber, for thereason that the sediment in the water to be filtered has atendency tosettle to the bottom and by passing it from the bottom the filter hasthe advantage of the specific gravity of the matter held in suspensionas it passes through the respective filtering-chambers, and the specificgravity of the matter heldin suspension assists the filter in holdingthat matter back to the inlet ends of the filtering-chambers.

When it is desired to clean the chambers, the fiow of the water throughthe medium of the valves is reversed-that is, ca used to pass downwardthrough the filtering-chambersand this may be done by having it passthrough both of the chambers simultaneously or through each of themseparately or be first filtered by passing through one and then throughthe other, and vice versa. The method of accomplishing this is asfollows: If it is desired to clean both of the filteringchamberssimultaneously, the valves 3, 2, and 10 are closed, while the othervalves are open, but, if desired, in addition to the closing of thesevalves just stated the valves 9 and 4 may be closed. In the formerinstance the water will pass through the' pipe G, the pipes R, andthrough the pipes S S and the upper end of the chambers, and in thelatter case the water will pass only through the pipes 12 and the pipesS and S', as may be desired and as will be readily understood. By theproper manipulation of these valves it will be readily understood thateither of these filters may be separated, and in the cleaning operationof them, separately or otherwise, the valves or plugs g are opened atthe bottom of the combined supply and settling chambers E, and the waterthen will pass through these opening and into suitable receptaclesplaced therefor or by a suitable connection into the sewer. The fiow ofthe water in the cleaning operation will be regulated, as will bereadily understood, by means of the valve Z, and the water can be madeto have its reverse passage through the chambers until clear water issupplied through the plugs or valves.

Should it be desired to filter the water before it is passed to thefinal-ltering chamber B for cleaning purposes, the valves can beregulated so as to accomplish this purpose, or should it be desired tohave this water pass through the final-filtering chamber B before itpasses to the primary chamber A for cleaning purposes this can be alsoaccomplished by a proper manipulation of the valves. e
